<pre><code>gem install colorize

<h2 id="overwriting-console-output"><a name="overwriting-console-output" class="plugin-anchor" href="#overwriting-console-output"><span class="fa fa-link"></span></a>Overwriting Console Output</h2>
<p>It&apos;s awesome to have more flexibility  in your terminal and sometimes we need to do more and with our scripts.</p>
<p>Overwriting console outputs makes our applications elegant and less noisy for repeated outputs like counting and loading progress bars.</p>
<p>I&apos;ve read a how-to about <a href="http://www.tldp.org/HOWTO/Bash-Prompt-HOWTO/x361.html" target="_blank">bash Prompt cursor movement</a> and I found it it&apos;s convenient to have it in our scripts. Here what have been said so far</p>
<pre><code>- Position the Cursor:
  \033[&lt;L&gt;;&lt;C&gt;H
     Or
  \033[&lt;L&gt;;&lt;C&gt;f
  puts the cursor at line L and column C.
- Move the cursor up N lines:
  \033[&lt;N&gt;A
- Move the cursor down N lines:
  \033[&lt;N&gt;B
- Move the cursor forward N columns:
  \033[&lt;N&gt;C
- Move the cursor backward N columns:
  \033[&lt;N&gt;D
- Clear the screen, move to (0,0):
  \033[2J
- Erase to end of line:
  \033[K
- Save cursor position:
  \033[s
- Restore cursor position:
  \033[u
</code></pre><p>So to test that I did the following PoC </p>
<pre><code class="lang-ruby"><span class="hljs-comment">#!/usr/bin/env ruby</span>
<span class="hljs-comment"># KING SABRI | <span class="hljs-doctag">@KINGSABRI</span></span>
